I need to create a coloring tool, for a sick children's portal, where I can lay a vector outline on the screen and the kids can color it. It doesnt have to always be 'in the lines' so a background image would be fine. That part is no problem...
However I don't even know where to start on how to make a took that when the mouse button is depressed it starts to draw (or color) a line. Any ideas where I can get a tutorial or a source code block for that? Thanks!
